由于Ubuntu16.04，自带Python2.7和Python3.5

当我安装完Python3.6.5后,terminal终端打不开了,

jekay@jekay-pc:~$ gnome-terminal
Traceback (most recent call last):
  File "/usr/bin/gnome-terminal", line 9, in <module>
    from gi.repository import GLib, Gio
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 42, in <module>
    from . import _gi
ImportError: cannot import name '_gi'
Error in sys.excepthook:

    import apt
  File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

Original exception was:
Traceback (most recent call last):
  File "/usr/bin/gnome-terminal", line 9, in <module>
    from gi.repository import GLib, Gio
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 42, in <module>
    from . import _gi
ImportError: cannot import name '_gi'

处理方法:

1: Ctrl+Alt+F1 打开系统终端

2:进入默认Python3 gi 目录

jekay@jekay-pc:~$ cd /usr/lib/python3/dist-packages/gi/

3:复制两份文件,重命名,将版本3.5换成3.6

jekay@jekay-pc:/usr/lib/python3/dist-packages/gi$ sudo   cp    _gi.cpython-35m-x86_64-linux-gnu.so       _gi.cpython-36m-x86_64-linux-gnu.so
jekay@jekay-pc:/usr/lib/python3/dist-packages/gi$ sudo   cp    _gi_cairo.cpython-35m-x86_64-linux-gnu.so      _gi_cairo.cpython-36m-x86_64-linux-gnu.so
 
4:Ctrl+Alt+F7回到桌面

OK,回复正常
